A moth ago, I felt something wrong with my gearbox, it was splipping. I thought it was because the PDF regeneration process was on, but it did not make sense you do not have control of your vehicle you accelerate, the engine rev but not encrease the speed.

After experimental the same problem sometimes always when I drive the frist time of the day, I was looking for online this kind of behavior finally I found in this forum a thread about this issue but it was dead and no have solution.

I would like to know if someone has had the same problem? And what was the solution, maybe reprogram?

I recall -- but didn't turn up in a search -- another poster whose transmission did something similar with a high rev. I think they also got an error message, though. If memory serves it turned out to be a loose cable or faulty sensor causing the car to think the transmission fluid was low and the car compensated by seeking a higher rev for than normal for the same speed/power target. Maybe something similar?

I wonder if it is involving the oil temperature, possibly the sensor. Don't know the strategy on the latest boxes, but earlier ones would not lock up until there was a bit of heat in there.

Hi kitercarlos: please see my pm about this issue. It sounds like you have the same problem as I had. Replacement of the mechatronics unit finally got the gearbox working properly. I was fortunate to have a good dealer whose team was determined to get to the bottom of the problem.
My thread on the problem was this: http://x3.xbimmers.com/forums/showth...hlight=colojim which you have already seen. I shall complete the thread with a final update (hopefully it will be the end of the story).
